Forum: NGINX Nginx Filed Descriptor are increasing in n*n space complexity

HI,
If I increase nginx worker count. File descriptor count are getting
increased in n*n oder.
Example with 10 worker.
 2 0xffff8801c4dec000
     10 0xffff8801c4dec300
     10 0xffff8801c4dec600
      2 0xffff8801c4dec900
     10 0xffff8801c4decc00
     10 0xffff8801c4decf00
      2 0xffff8801c4ded200
      2 0xffff8801c4ded500
     10 0xffff8801c4ded800
      2 0xffff8801c4dedb00
     10 0xffff8801c4dee100
      2 0xffff8801c4dee400
     10 0xffff8801c4dee700
      2 0xffff8801c4deea00
     10 0xffff8801c4deed00
      2 0xffff8801c4def000
     10 0xffff8801c4def300
      2 0xffff8801c4def600
     10 0xffff8801c4def900
      2 0xffff8801c4defc00

These are unix socket pairs intended to communicate between worker 
processes.
Actual number of sockets is N but not NxN because they are shared. 
Sockets file
descriptors are indeed NxN, but the file descriptor is more cheap kernel 
object,
than socket or inode/vnode objects.
